Hello!

You are creating awesome asset packs! I saw that some of them have CC0 license. It is good because free/libre assets help people to create their games especially it is very useful for beginners. Thank you for it!

Many people can find your assets through "free" filter that means free in price. Many of them are free in price but they don't allow you to use them in any way want. Some people search game assets by license but itch can't show your assets there because it just don't know that they have CC0 license. Itch will know it if you will set metadata for your assets. It will help you because it will show your assets for bigger audience. It will help people that are looking for good CC0 assets.

So you need to following the following steps to add it:
1. Open page of your asset pack
2. Click "Edit asset pack"
3. Click "Metadata"
4. Click "Release Info"
5. Choose CC0 license from the drop-down list
